Title: Magneto-optical recording method
Inventor: KOBATA YOSHIHIRO
IPC: G11B5/02
Filed: 1986-08-07
Abstract: PURPOSE:To perform what is called overwrite by making the recording magnetic field opposite between the N-th recording and the (N+1)th recording. CONSTITUTION:Upward magnetized bits are indicated by oblique lines, and downward magnetized bits are indicated with white frames. Two bits are used to record one signal '1' or '0'. In case of the N-th recording, the recording magnetic field is preliminarily applied upward and only pertinent bits are magnetized downward in accordance with signals '1-1-0-0' to be recorded. Then, in case of the (N+1)th recording, the recording field is preliminarily applied downward and only pertinent bits are magnetized downward in accordance with signals '1-0-1-0' to be recorded. Thus, it is unnecessary to erase recorded signals before signals are recorded, and only 1/32 rotation of the disc is required for recording of signals on one sector, and therefore, the erasing and recording time is shortened.

Title: Semi-super wide-angle zoom lens system
Inventor: ONO KAZUNORI
IPC: G02B15/16
Filed: 1989-07-19
Abstract: PURPOSE:To easily form a semi-super wide-angle zoom photography system while maintaining excellent image formation performance by moving the object- side negative lens element of a 1st lens group toward the object side and correcting an image point position by a 3rd lens group. CONSTITUTION:While the positive convex lens component A in the 1st lens group 1 in a wide-angle end(W) state is fixed, the object-side negative concave lens component B is further moved toward the object side so as to obtain a wide angle by forming shorter focal distance in the state of the wide angle end(W). At this time, a 3rd lens group 3 is moved slightly toward a stop S so as to correct the image point position. The movement quantity of the negative concave lens component B is determined by desired semi-super wide-angle focal length fsw and the lens power (1/f1 concave) of the concave negative lens component B. Consequently, zooming from the wide angle side to the telephoto side is normally possible and while the excellent image formation performance is maintained, the semi-super wide-angle constitution is obtained.
